Cryogenic dual-temperature low noise amplifier in K band

Future ground stations will require a high level of operational flexibility and, for this reason, the possibility to adjust their receiving performance (i.e. signal-over-noise) is beneficial. This study presents an approach to achieve this flexibility based on a dual-temperature low-noise amplifier,...
